HIN GED LOCKING CAP FOR COLLAPSELE CONTAINERS Robert L. Bedle, Augusta, Ga. Application March 23, 1932, Serial No. 600,663

(Cl. zzi-so) 3 Claims.

This invention relates to a hinged two piece self-locking cap for collapsible metal tube containers, such as are used conventionally for shaving cream, tooth-paste and like materials, which are intended to be dispensed-through an end of the container as the latter is collapsed.

One of the objects of my invention is to provide a cap in which the opening and closing is facilitated and accomplished by the use of but one hand, thus leaving the other hand free.

A further object of my invention is to secure the cap and thus guard against loss of the cap from the container.

A still further object of my invention is the provision of an improved device which will minimize the risk of contamination and insure adequate closing of the tube so that its contents will not sufier deterioration.

The preferred form of my invention is illustrated in the accompanying drawing, in which Fig. 1 is a side viewof the device with the cap cover open;

Fig. 2 is a similar side view with the cap cover closed and locked;

Fig. 3 is a top plan view with the cap cover thrown back fully open;

Fig. 4 is a front view with the cap cover closed and locked as in Fig. 2 and Fig. 5 is a rear elevation of the same.

In all views, 1 is the base which is in the form of a collar internally screw-threaded to match the threads customarily found on the neck of a collapsible tube container and by which the ordinary cap is attached. The improved selflocking cap thus takes the place of the ordinary screw cap.

The collar 1 has the hinge member 4 at the top. The top of the collar 1 also has an internally bevelled edge 6 to form a valve seat for the cover.

The cover 2 has a hinged portion complex'nem tary to hinge 4 and its under surface has the protuberance 5 with an external bevelled edge to fit perfectly into the internally bevelled edge 6 01' the base 1 when the cover 2 is closed down upon the base 1.

The spring wire 3 of the locking device has the two ends thereof securely imbedded in the cover 2 at its front edge as shown in dotted lines in Fig. 1. As illustrated more particularly in Figs. 2 and 4, the mid-portion of the spring wire 3 is bent and connected with the ends by sharp angle bends. The mid-portion of the spring wire 3 fits within a horizontal groove 7 across the front of the base collar 1 and thus forms a locking device for the cover.

When the cover 2 is closed upon the base collar 1 and locked, the face of the protuberance 5 will contact with the top of the neck of the container on which the base collar 1 has been screwed and thus form a secondary or additional check against the contents of the container escaping.

What is claimed is,

1. A cap for a container comprising a collar internally screw-threaded for attachment to the container, a cover hinged to the collar for interfitting closing engagement therewith, a spring wire having its ends imbedded in the front edge 7 0 of the cover and its mid-portion bent downwardly therefrom, said collar having a groove across the front thereof for engagement by the said wire.

-2. A can for a container comprising a collar internally screw-threaded for attachment to the container, a bevelled valve seat in the collar, 2. cover hinged to the collar, 9. bevelled valve portion on the cover for engagement with said valve seat, a springwire having its ends imbedded in the front edge of the cover and its mid-portion bent downwardly therefrom, said collar having a groove across the front thereof for engagement by the said wire.

3. A cap for a container comprising a collar internally screw-threaded for attachment to the container, 9. cover hinged to the collar for interfltting closing engagement therewith, an angularly bent spring wire having its ends spacedly imbedded in the front edge of the cover, and its mid-portion bent downwardly therefrom, said collar having a groove across the front thereof for engagement by the said wire, said wire being angularly bent between its mid-portion and each end at points outwardly spaced from said groove.
